Preparation method of waste incineration fly ash and asphalt cement test piece and adhesion evaluation method of waste incineration fly ash and asphalt cement test piece

The invention discloses a preparation method of a waste incineration fly ash and asphalt cement test piece and a method for evaluating the adhesion of the test piece, and the research method comprises the following steps: preparing a waste incineration fly ash particle-asphalt cement test piece, and representing the distribution form of fly ash particles; defining and analyzing a unit fly ash adhesion mass value alpha, an adhesion rate beta and an invasion microspur dq, carrying out primary evaluation and reevaluation judgment on the adhesion of the interactive interface, and if the reevaluation requirement is met, carrying out subsequent steps; preparing continuous group and discontinuous group waste incineration fly ash plane-asphalt cement test pieces; carrying out bonding strength and shearing strength tests on the test piece, and determining a bonding strength stable value phi and a shearing strength stable value theta; and reevaluating the adhesion of the contact interface. According to the research met
